Take the alcohol out of your game...
It adds a false sense of confidence. It also makes it hard for you to remember what lessons you've learned from a night out.
When I go to the local dive bar I order water.
I don't know what your appearance looks like, but your cloths will have to be some what in fashion. (Not saying your not my friend.)
Your verbal game is waaaaay off,lol. I mean really your coming from a frame of "Im not entitled to talk to you".

Youtube has some good examples of game. The best way to learn is to first emulate someone with the experience.
Justin Wayne (daygame) and Tyler from RSD (nightgame) have excellent examples of game I suggest you look into them if you havnet already...I've looked into Brent Smith,David Deangelo,David Wynant,Etc, and my honest conclusion is learn from Justin and Tyler.
